To all whom it may l'nnum:

Be it known that I, SAMUEL ll; Zrnunu, a citizen of the United States. residing, at. Oakland. in the county of Alameda zind State of California. lave invented new and useful Improvement s in Reinforeed (olwrete (onstruetion. of whieh the following is a smw-iliea tion.

My invention relates to i1nproyeinents in building and wall eonstrnetion.

It. eonsists in the eombinntion and arrangement or? parts, and in details of eonstruetion whieh will be more fully explnintfd by reference to the aeeompnnying dmwings. in whieh Figure l, is l1 ,view of a horizontal seetion of the wall.

Fig. 2 is a front View of a slab. Figs. 3 and 4 are enlarged \ieyvs ol' the tion of [he deviee.

' it is the objeel of my invention to provide no emnomieal method for rapidly eonstrni'ting walls ot eonerete and se -tiring sn'id walls in position.

in the ordinary eonstrnetion ol' eonerete walls, molds are built of boards upon eateh side, and the walls made by filling in emu-rote belween'these boards. and allowing li to sl'l. alter Wlllt'll the boards are removed. .\\"ull.-' are also built of in s or bloeks ot' eonerete told one upon the otlu r. i

In thi invention. the wall is eomposed of a series of labs whieh may be formed at oily point. as in a manotaettiring yard. where these slabs may be readily and eonveniently made in large sizes. and afterwards emu-eyed to the point of use. These slabs may be made'ot' any desirable length. sneh as the height between the floor and eeiling. add may hare any desired width and llliekness. 'lhus lhfe "l maybe llltltltlll a width equal to the ordinary di. .anee la-lween'the studtling. 'lhese slabs are formed with grooves or ellannels 2 made on the vertieal edges, and so eonstrneted that when the stubs have been set. up in line joint. Fig. 5 illustrates an applies-J with the edges abutting, the portion oeenpied by the,

- eha'nnels will register with eat-h other. These (llilll' nels' may be made eln'ved or anguliir, and when put together theinterior portion is of larder diameter in the dir -(lion of the lenglhol' the wall than the point where; they open outward ut one sidebl' the slabs. I

ln t'he l'orn talion ot' the slabs. rhds Ii are inserted extending vertieally, and wires t are eoiled around these rods al eertain distant-es apart; these wires extending transversely from edge to edge of the slabs and buying the ends projeeting into the ehanm-ls 2 to sueh at length tbnl tbey may be twisted and seeured around \tl'lltlll rolls-or bars whieh are set up in these eha'nnels when the wall is being eonstrm'ted. ln building a, wall u serit-sot'theseslnbs mi sol up in the line of theyvall. the openings or ehannels 2 at the edge of eat-h slab registering as shown in horihontal seetion. (om-rote or any suitable binderis then introdneed through the narrow opening, filling the space vertieally from top to bttem, and by reason of the enlargml interior portion it forms when set, a loek and binder whieh unites the slabs into a continuous solid wall.

The rods 5 are held in position so that they will not be displaced by the fillingin oi the binder, and before this filling is placedin the channels, the projecting ends of the wires 4 are coiled around the rods 5 and twisted together sethattthe whole structure is firmly loeked ,hy the. wires independent of the binding material. When this latter is added it will be seen'that the structure is homogeneous, and ii practically integral wall is formed.

The'slabs may be much more mpidly set in position than if the wall is to be laid up of separate hrieks, end it is also easier of construction than if built in the usual manner of building concrete walls.

In order to apply the finishing plaster or other surl'nee (i, I have, shown furring strips'l" of suitable thickness. When the ehannels 2 are tilled with the cement,

wire neils or other devices 8 are embedded in the filling material, projecting out through the openings of the ehannels. when the filling material has properly set,

the inning strips 7 are secured by driving them upon the points of the projeeting nails 8, and the ends of these nails may be afterwards bent down and elenehed so as to loek the 't'urring strips tirmly in place. Any

suitable lathing such as wire, expanded metnlor wood, may be attuehed to those inrring strips, and the plaster surt'aee (5, is then applied in the usual manner. The-- thiekness, of the furring strips is sueh that a spaee will be left between the main wall and the plastered surl'aee, and this spaee may either be illed with a denim im, material, or it. may be left open so theta. circulation of air can take plat-o; the air spare serving a similar purpose of preventing the transmission of sounds, and it also allows the walls to he kept dry by reason of the air eireulution. It. will be understood that: floors may be luid with these slubs extending between nnd supported upon girders as at 9, and the slabs may be arehed as shown at l0, and the ehnnnels or spar-es 2 will be loented al. the top {ind meeting edges of the slitbs. The wires 4 arid the rods 3 may be inserted in the same manner in these tlnbs und in some forms of ('onslrnetion the rods or wires 4 extend out through the ehannels in either direction, and maybe bent around or seeured to the upper members of the girders t). The ends of the thinsverse wires projeetim, into the ehunnels between-the slabs, are ztlso t-wisted'uround the heads of the nails 8, so as to'loeh them in pln efaud prevent. their being loosened or withdrawn by any twisting or wrenehing' that. may ocenr.

It will be understood that any desirable form of grooves ,or reeosses may be made in the eontiguous edges of the slabs so that. when sueli slnbs are set up and Having thus described my invention, what I claim 5 and desire to secure by Letters Patent is 1. Walls or floors constructed of integral slabs having vertical and transverse reinforcing rods and wires. channels made at the edges of the slabs having rods extending lengthwise thereof, around whichthe transverse wires arewound and securedfnails arranged at right angles to the rods and about which the said transverse wires are wound or twisicd, and a filling of binding material lnclosing the rods in the channels and the wound and locking the st: s together.

in a wirlhfltlohr and like construction, a series of lnicgl'al slabs having grooves or channels made at their meeting edges, rods extending lengthwise within said chunnc'ls, wires and rods molded into the concrete slabs when they are constructed said wires having their ends projecting so as to enter the channels hetween the slabs, and being wound around the rods to secure the slabs together, nails arranged at right angles to the rods and having heads proximate thereto and about which the transverse ,.\vires are also wound or twisted. and a filling of concrete or binding material within which the rods hi the channels and the headed ends of the naiis'and projecting ends of the wires are embedded.

.i. in a wall, door and like construction, integral slabs of concrete having rods and wires embedded transversely within them, said slabs having grooves or channels at their meeting edges, rods extending longitudinally of said channeis around which i'ods the projecting endsoi the portion of the nails wires are coiled and secured, a filling oi concrete or binding grooves or channels at the edges, means for securing the.

projecting ends of the wires to bind the slubs' together, a iiil ing of concrete binding material, nails embedded in said filling, said nails having headed ends proximate to the rods and about which heads the transverse wires are wound or twisted, said nails projecting outwardly having iurrlng strips secured to the projecting ends of the nails, lathlng supported upon said iurring strips forming an open space between the slabs and the lathlng, and a finished covering of plaster secured to the wall.

in a wall, floor and like structure, integral concrete slabs having longitudinally registering grooves or re- ('esses between their meeting edges. rods extending through the slabs parallel with the recesses, a iilling of concrete in ,said recesses, nails having their heads embedded in the said cement tliling, transverse wires embedded ,in the slabs with their ends projecting into the recesses, and wound or twisted about the rods and the nnli'heads.

in testimony whereof I have hereunto set my hand in presence 01 two subscribing witnesses.
